free bump at the least, you should troll or just pm an existing member who has posted about running similar setups in the various 79xx mining threads, who knows lots of nice people willing to help you out.

I'd assume you're issue is porting the new drivers for the 79xx series cards, I also heard it took a while for a stable driver to appear, but yeah troll the threads, it doesn't hurt to try as long as you ain't over volting lol

Yes. Windows is unstable. Resource hungry. Gaining remote access to your mining rigs is a major pain in the ass under windows vs Linux. Lacks updates in a timely fashion (see the recent poclbm problems).

Mining is about money (for most people), why throw extra resources at a problem (mining for $$) when you don't have to? Why complicate things by using a heavyweight OS to accomplish a specific task that can be handled with half the resources and 10x the speed?

If you're searching these lines for a point, you've probably missed it. There was never anything there in the first place.

Maybe I am stupid for using windows on all of my 25 miners......but I have had great luck keeping them all stable. Most will mine for weeks on end with no issues whatsoever.

There are a couple that have issues, but even then it is only once a week or so.

I am lucky enough to have access to as many licenses as I need, so the cost was a non issue.

Err.. not really. I'm not trying to crap on your setup, but your MH density is atrocious. You are probably spending 3x - 4x as much on power as you need to, unless you get power for free? Even if you get power for free, and I know this is kind of hypocritical given the nature of bitcoin, but you are being environmentally irresponsible as well. This is something I consider when building a rig - I know I'm being environmentally irresponsible mining in the first place, but if I'm going to do it, I'm going to do it the cleanest I can. 2 cards per machine is not good. You should be running 6 - 8 GPUs per motherboard/PSU to maximize your profit and minimize power consumtion, otherwise you are just wasting vast amounts of power powering the other components that are functionally useless to mining.

So for that same $110 a pop, you could have purchased a 5 or 6 PCIe motherboard, cpu and ram. Threw on a 1200w PSU and mined 6 or 7 GPUs... replacing basically 3 - 4 of the machines you have now, saving a net $100 or so in the process. (Figuring $200 for a PSU, which may be a bit undervalued, at worst, it would be break even at $300 for a PSU).

Please show me the way. Would love to find GOOD hardware that cheap.

My power is hydro-electric, so I really don't care how much I use......it has minimal impact on the environment (in terms of usage).

A whopping $120 bucks for 4 slot mining rig (6 if you use PCI - PCIe adapters), giving you the ability to run up to 8 GPUs, though I would recommend 2 5970's and 2 5870's, maybe 3 5970's and 1 5870 depending on your PSU.

Throw in a rebated OCZ 1200w PSU for $225 and you got yourself a pretty rockin' system. If you wanted to spend a few bucks more, you can find a 5 pcie mobo and either beef up your PSU a bit (if you can find a 1400w) or use two PSU's and power 3x 5970's and 2x 5870's.

As for additional power usage, you are using up 3x - 4x required power per machine, so it's 300% - 400% of the required power for 6 - 8 GPUs respectively.

I have a couple mobo's I run 6 cards on, though since Linux has an 8 GPU limit, most of them are 5870's. Windows has a 4 GPU limit if I recall, or did they finally fix that glaring deficiency?
